Application filed May 19, 1914. Serial no. 839,635

To all whom it may concern: Be it known that .i, GNNIGYENSANIAN, a

subject of the Sultan of Turkey, residing at Green Island, in the county of Troy, State of New York, have invented certain new and useful Improvements in Shoemakers Sewing-Iiiachines, of which the following is a description, reference being had to the ac'-' companying drawings, forming a part hereof.

My invention relates to boot and shoe making machinery and has for its object to provide a machine for shoemakers use which will permit of the entire work of machine sewing, trimming, sand papering and polishing necessary in making or repairing boots or shoes to be completed without requiring the shoemaker to leave his seat.

With these and other objects'hereinafter explained in view, my invention consists in the construction and combination of elements hereinafter described and claimed.

Referring to the drawings:

Figure 1 is a front view of a shoe sewing machine having my invention embodied therein.

Fig. 2 is a top plan view of the machine shown in Fig. 1, with the sewing mechanism removed; and

Fig. 3 is a vertical cross sectional view on line b-b of Fig. 2.

In the drawings, 1 indicates the head of a shoe sewing machine of ordinary construction, in which the main shaft 2 is provided with the usual pulley 3 and hand wheel 4. This sewing machine head is mounted on a raised portion 5 of a table top 6 which is supported at opposite ends by legs 7 and 8 which are suitably connected by brace 9. The main portion of the table top 6 is arranged at a comparatively low level, so as to be easily reached by a shoemaker sitting before it in a chair of usual height. This low portion of the table top .is preferably made of greater breadth than in the usual machine so as to afford plenty of space for implements, nails, pegs and anything else needed in the making or repairing of boots and shoes.

On the leg 7 is supported a stub shaft 10 on which is mounted a fly wheel 11 provided with a crank pin 12 from which a' pitman 13 leads to a treadle 14 mounted to rock on rod 15, the construction being that of the ordinary shoemakers sewing machine. The flywheel 11 is grooved, as shown, and a belt 16 leads from the fly wheel to pulley 3.

The legs 7: and 8 are provided with for-' wardly extending brackets 17 and 18pmvided with bearings arranged a little below the level of the lower part of the table top 6 in which bearings is supported a shaft 20 which carries the rotary tools such as are usuallymade use ofin trimming and finishing a boot or shoe after the sole and heel are sewed or pegged to the upper, such for instance as a cutting trimmer 21, sand paper wheels 22 and 23 and buffing wheel 24:.

The shaft20 is arranged to be driven in any convenient way from the fly wheel 11. In the construction shown, the fly wheel is provided with a pulley 25 and shaft 20 is provided with pulley 26, the pulleys 25 and 26 being connected by belt 27.

The sewing machine is also preferably provided with a thread twisting device arranged to be driven from the main shaft of the sewing machine head through the hand wheel 4:. This thread twisting device comprises a hollow shaft 30 mounted in a bracket 31 secured to the sewing machine head having on one end a disk 32 which carries a series of pins onwhich thread spools 33 are mounted. The hollow shaft 30 is provided with a friction wheel 3 which is adapted to be driven by the hand wheel 1. In use, the threads from the spools 33 are threaded through the hollow shaft and are drawn out together by hand as wanted, being twisted together as they are drawn out by the rotation of the shaft 30.

Having thus described my invention, what I claim is:

1. In a machineadapted for sewing, trimming, polishing and finishing work, a table mounted on a stand having end supports, a sewing head carrying a belt wheel mounted on said table, a shaft carrying a belt wheel rotatably mounted in said supports and extending beyond the end of one thereof, a trimming wheel mounted upon said extended end, polishing and finishing wheels mounted upon saidshaft intermediate of the end supports, a double belt wheel mounted on one end support, a belt running from one belt wheel thereof over the belt wheel carried by the sewing head, a belt running from the otherbelt wheel over the shaft of the trimming and finishing wheels,

and a thread twisting mechanism mounted upon the sewing machine'frame and pr0- 15 vided with a grooved pulley engaging the Q hand wheel of the sewing mechanism.

This specification signed and witnessed this l3th-day of May A. D. 1914.
